The reason is to save method call overhead to retain/release/... if GC
is enabled (they are defined as noops in the GC case).

I think Richard has played with that. Some time ago I used libFoundation
extensivly with BoehmGC, that worked very well.

You have basically the same, unpredictable to find, memory related
problems whether you use GC or not, but anyway ...

The GNU gcc ObjC runtime has very good support for BoehmGC. Eg it can
even use Boehm typed memory and manage weak references. See the
features.texi file included in libobjc.
